I have the StrykeForce and I must say it is an awesome crossbow. Accurate and low noise (relative to crossbows) Low vibration, oh and did I say ACCURATE.
. It is a fantastic all around hunting crossbow do to its narrow A TO A and nice balance.
One piece of advice I will give ( umm make that 2 pieces of advice) 1.. Call David wyvern like the others said. Best phone call you will make in regards to crossbow info. I MEAN IT.
2. Get or atleast look at Hawke sport optics line of crossbow scopes. THey are the bomb. I mean that too. Ask David as he has these too.
Best of luck
Good hunting
Brian
