I have an opportunity to get a Bowtech Extreme VFT that is a 2003 carryover...I have shot the 2004 extreme and plan on buying it but getting the 03 model instead would save me quite a bit of cash...were there any changes from 03 to 04? Cam? Limbs? anything? I look at them and can't find anything different and I've heard there were no changes but I just want to know for sure!! Thanks for the replies in advance!!
