My two cents worth...if you generally like the stock seat but would like it to be just a little better, then Spencer's mod will probably work for you. If you're like me though and hate the stock seat, then don't bother with Spencer. Like others have said, you'll probably need a Corbin, Sargent or similar. I've had Spencer mod my stock seat and it is definitely better but still not even close to being a "long distance" seat. I've also had a Sargent for about 1000 miles and even that wasn't what I'd hoped for. Now I've got the Suzuki Gel seat and, so far, it's the best option for me. However, I still have comfort issues after just 150 miles so it might just be that the Strom doesn't fit me very well.
