I'm 6'-0" and just installed Scootmod 3" Forward Extension kit. I have not ridden wtih them yet since it is raining here today, but just sitting on the bike I can feel a world of difference. I'll let you know after tomorrow (I hope to get out if it stops raining). I would think the 3" would be fine.
Also I just posted some pictures from the project and some hints and issues I came across in another forum post.
