Not really. I actually shot the Speed Force at 62lbs and was pleasantly surprised. Almost zero hand shock and fast. The draw cycle isnt like the Switchback's. Not as smooth andnot much of a valley, but a very solid wall.
Of course, there are gonna be trade-offs.
I'm expectingaround #92 k.e. (vs. #73 w/ the Switchback)shooting 400 grn ACC 3-49s. I just hope they are stiff enough.
For me, it was worth the trade.
