you can ask 900 people and get 901 answers, fact is do not paste your only linen strop, if you use it daily, each time you wear the razor. I don't use any paste at all I use hones and strops a good stone to me is far superior to any paste I have ever seen.
I agree with this also. When my blade gets to where the strop wont fix it, I put it on the stone, usually 4k,8k,12k. If that don't get it I go all the way back to 1000k. I have the diamond spray and the crox but don't really see a lot of value in it
