Hello,
In principle you are right.
Being on site and for a few more euros, I prefer to order the active components (some are not on E...Y), at least I will have spare parts and this will avoid waiting 3 weeks for delivery.
For 4 euros more, I ordered also 2 curved nozzles, it will be easier to desolder.
Another question, do you have a site that references all models of nozzles, especially for SOT circuits. I did not find.
ex models 1131.1132,1133...etc is not relevant for dimensions. (4.8*10mm, 5.6/13mm, 7.5*15mm,...)
