It has always bummed me I cannot find a 22" bar for stihls. With most saws I can stand straight , no bending with the 22 " and just miss the ground with the bar tip. I use 20" the most and then the 24-25" second most . If I was in a bucket or climbing I'd go shorter, really big stuff I prefer a longer bar that I can reach through, would rather let my saw do the walking.
I've scarfed up a couple 22" bars with the hu mount that I intend on having milled to fit my stihls. Back in my early days I used old homelite c series, the 22" was always my favorite.
