Oh btw ... i'm kindda small and i found it kind of difficult to make nice greasers with C172s while i had no problems in all other A/C i flew at that time (Robin Remorquer, gliders, etc) .. i finaly found out that i was sitting very low even with the seat all the way forward so my vis over the nose was very restricted. I fixed that (pillow) and voila the "bumpy landing syndrome" cured ..
Actually got a LOT better when i went for taildraggers.. since then i don't need to see over the nose no more
