Can someone give me a hand. I need a guide to create a preflop strategy HU SNG with 25~18bb.

I should also have a limp range right? Probably just a small part of the opening range.

OR: 75% linear
OLimp: 5% polarized (50% AK,QQ+) + (low off suited connectors, 54o, 43o, 32o) or something like that.

Is this OK ?

I only need this opening ranges. The rest I'll figure it out.
