hey there, i bowl on both type of approaches, one thing i do before i even start bowling, incl shadow bowling, is that i walk the approaches, to get the feel of them. im also a stroker/tweener, and im very dependant on my footwork so i always check the approaches, from gutter to gutter, especially the last 3 feet or so to check for tackiness. i look for footprints, etc. if i find a sticky part, i just wipe it down with my towel. also experiement with your sole/heel combo. one thing i also notice is that when you switch to new soles and heels, they may give you more brake or slide than you expect, but once you break them in, they beoome a little more consistant from week to week. but very important "at least to me" when you start your shadow bowling, take your first few shots slowly, to see what the approaches are like, and adjust from there. sometimes its easier to adjust your footwork a pinch, by starting slowly and building up to regular speed. it usually takes me a couple of ball on each lane to get the feel of the lanes. oh.. also pay attention to what they do to the approaches before you bowl, i.e. do they mop then down before bowling, lay powder on them, use spray cleaner, etc. i knew a house that would mop the approachs down before bowling, and then run a dust mop with what seemed like easy slide on the lanes. and some houses use some type of spray, maybe furniture polish or silicone based spray to clean the sticky spots.
SO CHECK THE APPROACHES BEFORE YOU BOWL.
i hope this helps.
