SimonTheBeetle: And I'm not sure the reason why I feel NIKE Vapors & RSi2s practically the same is due to the fact that I play on mobile.
I don't think it is, the attributes of a club don't change just because one is playing on mobile. As for those 2 club sets being "practically the same," this is just not true. There are no jets firing here, I just don't know how to make it any plainer. The only similarity is in the 3, 4 and 5 irons-those clubs play the same. However, the 6-PW don't.
What WGT did when they introduced the Vapors was to enhance that part of the set so that the lower 2/3s of the irons performed the same as the top 1/3 on top of increasing both the accuracy AND the forgiveness. That part of the difference is huge.
A prime example of the difference is the PW. The Vapor PW is the equivalent of another CG and will spin back off of a green if you're not paying attention. The middle and low irons of the Vapors are well ahead of the TMs in accuracy and spin control.
