To be honest, I would spend more time shooting your bow at the moment, than considering splashing a load of cash on fancy grips.Here are a couple of pictures of my riser. Any advice on grip colours to match?
You've said before you've only been shooting 5 or 6 weeks, and only shot your bow a couple of times - worry about getting the basics right & nailed into the subconscious etc before starting to mess about with things...
Once you have been shooting for a decent while, you then understand the limitations etc of your kit, and how it could be altered to best assist with your style of shooting.
Don't try to run before you can walk....just shoot!!!
