Welcome. I'm close to 250 lbs. and put the stiffest springs on front and back from procycle. Some say putting the front fork emulators are better than just the bigger spring but I have no experience with that. For me, the springs are better than stock but this is very subjective according to your use and riding style. For me, the TW does ride more rigid or stiffer but I don't get the bouncy bouncy pogo rear end bounce I got with the stock rear spring (as much).
Here is the procycle spring (left) versus the stock spring and spacer (right).
Here is the stock rear spring (yellow) compared to the stiffer red spring. (Note: My TW is a 2015 and I've heard the newer TW's, 2017/2018? maybe have a different style rear shock).
Red stiffer spring installed on the shock with a DIY spring compressor. Extreme caution should be used when using any DIY spring compressor. I've never had a problem but some people lose a finger, toe, or other body parts just walking across the street so I thought I'd better include the caution statement.
