Leafy frosty buds. How to harvest trichomes off it

Bud would take too long to trim. Have about 1lb of it.

Whats the easiest solvent free way of utilizing all that trim?

Pollen,tumbler or ice water hash?

I love Ice water myself, but the 8 bag 5 gallon bag set is a little time consuming and TEDIOUS for sure, so maybe NOT what you are looking for... I am unfarmilar with the other two methods you mentioned... and you would not be able to do the whole thing in one go of it with the 5 gallon set. I wouldn't try more than 2 zip per pass but someone else may know better as I have never handled that kind of weight myself.
