Just finished locking ITMX. I remember this from last time, but just wanted to record some of the difficulties with locking the ISI's from below, in their current configuration. The ACB is VERY in the way (it's guaranteed I bumped it a few times), so I have to basically lean out over it a little (my spine does not make the proper S shape to make this easy) and Betsy's stool is a little too tall to slide under it. It would be a little easier if the current in-chamber stool was ~1 inch shorter, making it possible to slide under the ACB. The TCS mirror is also in the way, but it's manageable to work around, don't know if I touched it, I couldn't see because my head was jammed between the chamber side and St0 of the ISI.
