The derailleur is smooth when shifting from the 11th cog through the 14th, and starts to get a little clicking sound from 15, 17, 19 & 21. then 23, 25 & 28 appear to be fine, not sure if this a result of bent derailleur or not

    CX; I like your setup and appreciate your input, but I can't justify the spend.
    If it's a bent hanger (bent in from falling on derailleur) it will get worse as you shift to bigger cogs...it won't ever get better, only worse. It turns into a geometry problem cuz it's a triangle now instead of 2 parallel lines. The cogs and the pulley cage should be parallel...the cage being vertical when looking at the bike from behind, not angling in towards the spokes.

    This is the one I was taught to use back in the 70s. The old mechanics at the bike shop called it the "Campy kickstand".

    https://www.ebay.com/c/1737212941

    It worked fine in the pre-indexed shifting days.

    The one I use at the shop these days is made by Efficient Velo Tools of Portland (I am not one of the mechanics, but will often correct a misaligned derailleur so as to not add to the mechanics' workload):

    Life is short... enjoy the ride.

    I've used the Campy tool a bunch, it's a classic. The EVT is amazing like everything they make. Not sure about $500.00 amazing but it's super nice.

    I don't have the best eye when trying to look at thing up close, and could be my eye's playing tricks. But it looks slights kilted outward and not inward.

    My bike has fallen on the derailleur in the past month as my daughter was trying to move the bike and make room for her dance classes... yes my office/bike area has now become her virtual dance class room as her studio is continuing with classes and trying to stay positive for the competing seniors.. but that's a another topic/story for another time!

    Bike falling on the drive side is probably most common way rear derailleurs go out of alignment. Although I once had a clueless idiot bump my derailleur with his front wheel which bent the hanger.

    So quick follow-up.

    My alignment derailleur arrive yesterday... used it this afternoon and found the derailleur was bent not only vertically but horizontally as well. Made a few tweaks in both alignments using a 3mm Allen key as guide for spacing between the edge of the rim and the end of the indicator rod. Everything at this time is shifting very smooth.

    I now agree this tool is definitely one to have in the tool box

    This sorta depends on the hangar. Some are very soft, and will bend with the slightest bump. I've even seem them twist. On the other hand, the one on my Moot's is so stiff it's uncomfortably hard to adjust. The nice thing about this is, once I got it where I wanted it, I don't think it's going anywhere.

All 3 of the ones you linked to are probably garbage...the Park and the other one that looks like the Park are definitely crap. The green HAG in my box from https://www.abbeybiketools.com/products/hag is hands down the best one made. Worth every one of the considerable number of pennies you'll pay for it. Easily my favorite tool.

    Abbey bike tools HAG and Crombie FTW. Worth. Every. Penny. I used the Park for years and the HAG is WAAAAAY better. "The right tool for the job" is rule #1. Most here are paying >>$3,000 for a bike (and some upwards of $10K) plus upgrades and accessories. Good tools are a cheap investment.
