Had you actually posted that last line in your OP, I probably wouldn't have even posted. Withholding information only hurts your chances of getting the assistance you want.
What's the highest ABV beer you've brewed so far? Do you have the hardware (and knowledge) to make starters? With a proper sized starter, using pure O2 to oxygenate the wort, adding yeast nutrients, and a few other techniques you can typically get a few more ABV points from a yeast strain. Just remember, fermentation temperature is going to be extremely important here too.
I mentioned the wee heavy since that's what I used 1728 in. You're not locked into JUST using it in wee heavies (or other Scottish ales). IF you really want to get the highest ABV from the batch, you could always try WLP099.
I would use it at the low end of the temperature range. So, keep it <65F for the duration. Going too warm with that strain can produce unwanted flavors. Of course, it's probably not a good idea for a novice.
