| I bought my setup 4 months after i started archery. My scores went up immediately. Despite what alot of people saying, switching from beginners kit to better kit WILL help, but it's not magic. You were asking about the limitations of the kit. There's a misinterpretation here about what people mean. The fact is when people talk about how 'good' kit is, alot of the time they're talking about how consistent it is if you shoot like a machine, exactly the same each time. In this sense beginners kit won't be as consistent. But this is irrelevent to most of us as we DON'T shoot exactly the same each time.
The most useful info i can give you is that better kit will help YOU to be more consistent, by allowing you to draw with less effort using smoother limbs, and allowing you to be more relaxed because you like the feel of the riser in your hand and the way it reacts after the shot. Also having arrows tuned to a bow of the right length and poundage for you really will help as soon as you approach anything that could be described as intermediate level.
I bought my setup because a) i knew having my own bow that matched me would give better results then one not set-up for me and b) because i wanted something that i was unlikely to grow out of ability-wise and would have a fairly good resale value should i ever give archery up.
Basically, you are unlikely to shoot well enough for the kit to be the limiting factor in quite a long time, but better kit will help you progress more quickly  |
