What timing.
I used these strings for years and then went back to rounds. Just about two hours ago, I was digging through my junk box and came across a set that had never been opened. (I thought I had used them all.) Thought about selling them and then decided to try them again and tossed them on my passive P-J Schecter.
To answer your questions: I've never found the tension that great on these strings. In fact, I think they are a bit less than the Boomers I had on the bass. The biggest issue you will have is the diameter of the strings (the E is .115). Some bridges don't deal with that too well and, most of the time, you have to file out your nut slots a little bit to take these bad boys. One other item: since the strings are wrapped in nylon, they don't ground to the bridge. If your bass tends to buzz when you don't touch the strings, you will never get it to shut up when you have these things on there.
On the up side, these strings have low-mid thump for days.
Hope that helps.
