Jerks and Topwater sizes for smallies

[Dr G]

Well it's finally time to start purchasing some lures so that's why I'm asking all these questions. So here's one about choosing sizes for some topwater and jerkbaits. I plan to be fishing for smallies in clear northern lakes, late summer. The advice I'm hearing is that for northern smallies, keep the lures small. I would like to get 1 or 2 Lucky Craft Pointers, Flashminnows, as well as maybe a Sammy. I can't afford to be buying 4 or 5 of each of these and frankly don't want to load down with a ton of hardbaits anyway. But if it's true that I want to keep my baits small should I be thinking about real small like 2" or more like, say a Pointer 100, which, while a popular choice, would be quite a bit larger at 4"? Again, I won't be able to take a ton of stuff with me to try out so I'm hoping by mining your collective experience I can get better idea of how to make some intelligent choices.
