I think the main thing I will sugest to say-that I think designers confuse in order to how mixture goes to crancse-it doesn't go there by positive pressure-it goes by negative pressure created inside crankase and based on this I wouldn't see personaly any benefits of angled hole. About slots on buttom of sleeve-We will never make those slots to reduce friction-we just make right taper. The skirt of sleeve will start bending uneven (due tot he temperature difference between buster and exhaust on sleeve) and it will create more friction.
Again, it is my opinion and it doesn't mean I am absolutly right-let'see what will happened on tracks.
