With out a doubt Hawk. Especially the nose cones. They are top notch. My L-3 , 6in diameter is all Hawk. The quality of their spiral wound tubes is second to none.
Don't get me wrong I have 6 Pr rockets and value wise they are hard to beat.
If you want a Rolls you will pay for it! Either one will take anything you can throw at it motor wise.
A little more work to finish and get a good fit, PR is the choice to save some money. BUT I would buy through a dealer, not direct to alleviate any delivery and in stock problems.
