RE: Martin Bows???
Spike, the one thing I forgot to mention is that you should also pay attention to the brace height on certain models. The SlayR and Cougar mag are two examples. Really nice bows and fast with the Nitrous cams, but low brace heights. It usually takes an accomplished archer to get the most from a lower braced bow as they are less forgiving.
It's generally accepted that for a novice or intermediate expereienced shooter you should keep the brace above 7". For example, my new ShadowCat that is on order will have a brace of about 9". My SlayR is 6 3/8". I can shoot the SlayR well so I know the ShadowCat is going to be a dream.
Hope this advice helps.
