Hi, thinking of putting the newer style biquit with the slot to load arrow and the softer bristles onto my old rest. I don't really mind loading the arrow from the back so that is not an issue. What I want to know is if they help as far as speed,arrow flight, vane wear,etc. Thanks for any responses.

Yes, Tons better on all accounts.

Put the new style on last year. Much better all around than the old style

Same here ALOT better.

What about if you have the one with the loading slot? Is it worth 40 bucks for the new disk with the black bristles on the bottom?

ALOT better the new system will not dull your blades, that in itself is worth the cost of changing over.

I would tend to agree...definitely a noticeable difference in the wear on your fletchings as well as the reduction in arrow speed.

Amazing difference and hardly any trimming...I'd recommend it without a doubt.
