Actually, I use them, too. Haven't had any problem, though every time I tell someone they can do that, someone else comes along and says nothing below 1.2Ω...lol. So, I just stick with the 1.2 story. Tis simpler. When I do rebuild, I do it at my preferred 1.5 range.
GMTA (I had a feeling...).
I also have plans to do the exact same as you, once I begin rebuilding them (do they ever wear out??????). I plan to open up that range so I can use them more frequently on my 2.5's.
