FTM Steelix from IT/HS to DT/HS?
Of course, DT/HS is better on defence. What holds me back is that Steelix with IT/HS may be viable on attack. No Metagross yet, but I do have an Aggron, also with IT/HS, that I could power up. I also have more than enough (specifically, 19) FTMs. The gym scene in Singapore is very competitive and I seek more gold badges (despite lacking Chansey candy).

Steelix has zero offensive applications due to having such a low attack stat (148, same as Furret).
IT performs a bit better against Machamp, the most common attacker into Steelix, but honestly the difference between the movesets isn't great as long as the charge move isn't EQ. If you expect summer to be mostly clear and people packing a lot of fire-types for gym fighting, you could use an FTM and get DT.
Aggron deals significantly more damage than Steelix, 50 difference in attack stat. That's like saying Graveler is as good a rock attacker as Golem.
I don't advocate using Aggron for attacking unless you're seriously lacking in other options, but it's just incorrect to say it doesn't deal any damage. GPs article in the sidebar agrees with me.
