What do I look for when buying.

(I apologize if this has been posted before, I am terrible with computers)
I currently do not have the ability to grow though it will be in my near future. In that I am unfamiliar with weed in general. I smoke a lot and know what good bud looks like. Though in my extensive hashing career I have discovered that although using bud is important for making melty hash, choosing higher quality bud doesn't always make a higher quality hash. This has lead to disappointing results as I spent good money for stuff that barely melts.
My methodology is as closely replicated to the videos I have watched of bubble man. (Minus the bubble now). Because of this I only use medium grade bud when making hash.
As i said i don't grow which means buying 2 oz to wash through the bags, this is a lot of money and I would like it to go well tomorrow.

Is there something for me to look for as I shop today?

Can I simply magnify to look for trichs, (which i have never done before, though have seen all the photo's and know what to look for).

What kind of cure should the bud have? I read the YBG's experiment post on using fresh to make higher quality. Is this to say that I should be buying bud that still has moister in it?

I also read that less dense bud is good as it usually has better surface area and will float.

If any one could answer some of my questions or provide better advise to someone that is experience in making hash but inexperienced when it comes to bud, that would be much appreitated.
