Thanks for the recommendation. Unfortunately he isn't modding U2s anymoreI just had Vinh54 mod mine with a new emitter and I am very happy with it. Gained a little in the brightness but most importantly a huge improvement in tint and color rendering while keeping the same great beam pattern.
I messaged him a week or so ago. He mentioned they were very aggravating to work on.Really? When did you ask him? He just did mine like a month ago. He didn't say anything about it being terrible to work on, though I guess that's possible.
