Thanks, this is what I went with.
You happened to pick a good middle ground.
The UltraSkin medium hardness is actually on par with the Kamui Black soft.
I have played with and installed many of both and my input is that it
really doesn't matter. However....
Confidence is a key factor and if I play with a $5 tip or a $20 tip, I am confident the tip is doing what I need from it consistently.
All tips compress and get harder over time; this includes mediums. However, starting with a hard tip takes a stroke everyone simply doesn't have. That said, I replace my (soft) tips due to feel/hardness long before someone would consider them worn or low.
Personally, I also used Kamui tips when they were all the rage but I switched to Ultraskin when I was given one in lieu of a tip installation fee... I now use UltraSkin with confidence.
