Is there a practical use for Shino Exroad LG2 or LG3?

I was tinkering around today and tried to make a bot that used Shino legs, as I have 2 3 slotted LG3 and a 3 slotted LG2. I found the LG2 to be a little weird to melee with. The LG2 seemed a little weak for the cost, the third hit knocks the opponent away and it didn't seem to combo well with anything I tried to pair it with. The LG3 has a more powerful hit, but leaves you standing about for quite some time and doesn't have any combo on its own. So, are these parts without a practical usage, or am I just not seeing their true potential? (I thought about trying to Cartridge Step into a LG3 hit, but I really suck at switching weapons quickly.)

I tried Baron AM5 with LG2(RS+AM5+LG2 or AM5+LG2+K-shield), it's good if u keep on ground, LG2 has less delay time than AM5 and does knock back. But if u jump/on air, LG2 will do spin attack instead

LG3 is SS's rite?I think dual K-shield + nitro/cart step is good, it's like B.C with dual shield instead one
