You are going to have a very different "feel" with an ILF metal riser. Not talking performance, talking the feel of the bow from set up to follow thru.
What are you looking for? Performance, accuracy, traditional appeal, cosmetic appearance, etc? When you say better, what needs to improve?
The best thing you can do as far as shooting a bow and arrow is shoot one bow, and learn that bow. Not that model, that bow. Archery is a martial art and developing a flow and consistency will happen if variables like the bow change less often.
This many times leads to improved shooting. No kidding. Not what many people want to hear, but truth...
