Lefty,

The parker bows are excellent bows in my opinion. I am getting a new bow myself as soon as my tax money gets in. I have owner a Hoyt Magna-Tec and then a Supertec and I loved them both.

This year I looked at the new Hoyts and shot the Xtec, I have shot the Switchback and the Parker Phoniex 36. I must give the Switchback its props as it is a awsome bow but...... for the Difference in price I am going with the Parker probably a Phoniex 34. Iyt has awsome speed and is dead quiet as well. It is a super close toss up between the two but I will let my wallet buy this time!!!

To answer your question you can buy different modules to go on the cams as your draw length changes. Around here a new module goes for around $10 or $12 dollars... very little extra output down the road for a great bow from a great company
