Just go with tne in oil...water based suspension seems to leave a knot with me no matter what i do, and i'd rather have pain for a minute than a knot that lasts for a week and you cant shoot that muscle again.
I love suspension and have tried a number of sponsors here and on other boards and all bullshit aside I would have to say Motorboant suspension is the shit...a little pain going in but no knotting or constant pain at all
