Hi [USER=15576]B0B4F3TT[/USER]
That's kinda funny, I also was originally going to do an ESB too. But for whatever reason, fell in love with the red gauntlets and color variations on the jetpack.
For size, you shouldn't worry about the helmet any. I'm a larger Fett weighing in at 235lbs and standing 6'2" tall. The VX Helmet I have has no issues fitting my large noggin. I have plenty of room and am actually thinking about upgrading it to wireless rangefinder. I will say this.....thee only thing you'll have to find for your helmet is a harness. And for that, I went back to my days I spent in the US Army ('94 to '04) as a Combat Engineer. I opt'd to get a simple PASGT (Personnel Armor System for Ground Troops) specifically the adjustable suspension system.
There was another post on this where a member was asking for a comfortable helmet setup. I chimed in and gave a lengthy reply (like I did here) about it. Take a look at that post!
Here's the link: Most comfortable way to secure a Boba Fett helmet on your head?
Also, I did a full write up on my entire ROTJ journey to date (Still ongoing) it is about 14 pages long and filled with plenty of pictures and heavy descriptions. If you have any questions about that post, or something I didn't cover let me know.
But here is the link to my WIP: Iron's ROTJ WIP
Enjoy!
