Question about Int Stack Kinetic Blast with Possible Bolt of Fragmentation

I am new to Int Stacking, but I enjoy how intuitive it is to progress. More Int = More damage. I am not fully geared, not by a long shot. Half winging it, half looking at inspiration.

I am noticing a lack of Boss killing potential right now. I am aware how the Merc with -Lightning resist and a Nimis should help alleviate that, I was curious on going a different path.

I saw someone make a pseudo 7/8 Link set of Gloves with Kinetic Bolt for boss killing, while having Blast on the 6 Link Chest for clear. I looked up how to make the gloves and I am confident in crafting a 7 link. 8 is far out of the question unless I make it big.

Will that work? Would Bolt with a 7 link on gloves scale with Int Stacking? Would it be a noticeable different in boss killing damage or would I be sacrificing too much for it?

I am very interested in try it, but I am not experienced enough to know if there is a flaw in it, or if Bolt and Blast scale differently as the player I am looking at isn't doing Int Stacking.

They used Fragmentation. Is that better than Baseline Bolt as well, or a different flavor with same kill potential?

Any help and information would be amazing. Thank you.
