RE: How much speed is enuff???
For starters that speed with that weight arrow is pretty good and more than enough to kill deer. I shoot a 450 grn around 200-220 fps and it works.
My question would be why did he get a switchback if he already had a legacy? That is a fairly new and nice bow. I don't get why he spent that much money on a new one if it was not what he wanted. What exactly was he looking for when he got it, and is he only unhappy about the speed?
If that was an issue with him he should have taken his old bow with him and compared the two side by side and shot the new bow with one his arrows at the proper draw length. That way he would know the aproximate speed compared to his old one. You have to keep in mind it may be a bit less after you finnish setting it up.
I would say it is not an isue with the bow so much as him just not doing his homework before he paid that kind of money. I won't buy a bow unless I get to shoot it first, and usually I get to shoot the one I am buying before I actually pay for it.
