I think there is far too much vibration coming from the tips of the wire loop that are not connected together during the shot on both this one and the regular twister, and you can feel it during the shot.
Kevin,
I am not getting that vibration that you are talking about? When I read your respose I went into the basement and took a small rubber band and wrapped the ends tight together to keep them from moving at all. (Accuracy was a little [:-]) but I couldn't feel any difference on my Liberty? I took it off and again, no difference and no vibration.
I too am just getting to know the design and am like you.......looking for a reason why I should or shouldn't like something. I do have the launchers completely wrapped in moleskin.
I did hear from somewhere (I can't remeber now who said it?) but supposedly APA is addressing the stiffness/thickness of the TWister's launcher probably to address what you found and what I did with respect to being able to bend them.
A few questions...
Without using the set-screw, how "tight" can you get the rest to the riser? Can you move it at all with your hands?
Is the rest heavy? It looks rather large, and I know that alot of guys don't like to have a heavy rest on the side of there bow as it changes the balance of the bow.
Have you tried any other vane/feather configurations? Will a 5" shield cut feather work or will it hit the sides?
Jason,
* I have the rest as tight as I can get it.......The only thing that bothers me is that I had to use the furthest mounting point which provides the most leverage to loosen the rest if it is bumped hard. I rapped on it quite a bit and couldn't get it to move. The mounting plate is fairly thin which I think helps. I generally don't like to jam set screws into the riser for resale purposes anyway, so my only real concern is the outer edge attachment point.
* Not heavy at all.......I think it may be lighter than my TT? I didn't weight it but I didn't notice any out of the ordinary weight.
* I have tried 3", 1.3" and 4" vanes on standard ICS style carbons (CX,ACC, Carbon Impact), and 4" helical feathers on my CXL fatter shaft carbons. No contact, but with the 4" feathers and those fat shafts there is very little room to play. It's tight. 5" shield cut on a big fat aluminum is gonna be close.
I think anything on an smaller diameter shaft will be fine for sure. Axis shafts would be perfect.
Is it easy to set it to stay up for the optimal 2+" of arrow travel required for the unlevel knock travel bows?
Dave,
Tuning for drop time is a breeze......that tuning screw makes it almost fun to play with different combinations. Because of the slide travel characteristics of my Liberty I have mine set this way: The rest hits its highest point with about 3/4" of arrow left to go........BUT when letting down the launcher supports the arrow for roughly 3.5-4" of travel before twisting out of the way. Arrow flight is terrific.
You also have 3 choices for the spring to provide more or less tension based upon how you want the rest to twist away.
I was just wondering if you have paper-tuned that rest, or shot broadheads with it?
Beav,
No I haven't with respect to either......I haven't settled on a shaft yet for next bowseason, so for the moment everything has been set to eyeball. Flight and groups are great and I'm getting no contact. That's all I'm concerned with until I have my hunting shafts ready, when I have them and serious practice is in the works I will tune carefully to whatever shafts I settle on.
Since the whole arrow has the pass trough that 'hole'....would it not interfere the arrow flight?
Did you test it with powder or dry shampoo ?
Raymond,
I did use foot spray (powder) for all the shafts I listed above with no contact........that is shooting cock feather down as I'm sure is intended for this rest. The hole seems a bit tight in the pictures, but looking from straight on its pretty large. My only concern would be very large diameter shafts with the largest fletch choices.
As with any rest that you would shoot through, special attention should be given to proper centershot and arrow spine.
