yes the low melting point is one bonus; the fact that it 'flows' so much more easily than manty others I have rtried is another. WBT make great solder too; but is quite expensive and TBH not really worth the extra money. It is better, but not THAT much better. with the lower melting point it means its less likely that you will scorch the wires or the dielectric between the poles in some connectors.
LOL yeah the neutrik sucks like that. make sure to sand off the sharp edges afterwards; as it is easy to slice up techflex or insulation sliding it over the braid or whatever. BTW you are starting with the mini arent you?? rather than starting at the dock end?? easier that way. get yourself some cardas flux as well if you can; not cheap but will last you a lifetime and the amount of time and stress it saves is IMO worth its weight in gold. you can get other flux, but i just find the cardas to be best. its no-clean too, so if you cant be bothered scrubbing with alcohol then you dont have to. I recommend once you get sopme more experience moving onto using epoxy instead of hotglue. if you are using the hot glue not just for strain relief, but also to stop the wire from oxidizing, then epoxy is far superior IMO. it rids you of the 'edit' function, but as long as you test connections first with a DMM all should be well.
you are gonna hate the canare; THE WORST MINI EVER IMO. sux to solder, ugly and too large to work in many rigs. I go switchcraft for most jobs, neutrik for cheapscates or cables that need to be small and XLO for the high end jobs. the switchcraft have a 6mm opening. but I usually drill then out to about 8. the XLO can be drilled out to almost 10mm and they have a non-conductive coat on the inside of the barrel too, so you dont have to remember to slide the tube on... which is usually too small for my work anyway. OH and the neutrik can be drilled out to about 6-7mm
good luck
