DW SP-024 Pedal Spring

I found that the spring had too much tension. I checked on the DW web site and saw that this is high tension but, the one next to it SP-020 was normal tension. The different was this one had the mounting hoop. I would have thought that they were the same spring. If you are going to buy one check to make sure of the correct tension. I'm struggling to play with the SP-024 spring even after spending a couple of hours trying to adjust it. I have now ordered the SP-020 from Thomann hopefully this will work.
