Convoy S4,6,&7

I ordered the S4, S6, and S7 since everyone here has so much to say about them. I got low/med/hi mode, with 7135*8 in two lights, the s7 is just a stock light, everything made default. There wasn't an option to upgrade the S7 from the seller. It's supposed to be a stainless steel light, so I had to order it!

I'm already getting an urge to modify one or more of these. Having never done such a thing with a flashlight, can you guys give me an easy challenge to get me started in the flashlight modding business to make the best throwing light I can make with the easiest modifications for a reasonable price? I want to keep it as simple as possible to ensure I follow through and get it done. All your flashlights I've been seeing are insane at 2500+ lumens, I'll save all that for a later date Lol.

I can solder, and I'm accoustomed to fabrication by nature and trade but I don't want to get in too deep right off the bat, so what would your ideal build be for a guy like me?

I made another thread here, probably more appropriate place to discuss this. Sorry I'm new.
