The New Zealander set up a try, busted two tackles and looked lively against the Black and Whites.
“We haven’t trained together very often, once probably,” Gale said.
“This is the first time we’ve played 80 minutes together, so it looks promising.
“It will probably take a bit more time but we’ve got some strike in our team and our defence was a bit better tonight, so I’m really happy with it.”
Gale was pleased with his side’s performance in beating Hull FC.
“We started really well and it’s always hard when you’re 0-24 up,” he said.
“You don’t take your foot off the gas intentionally but you sort of change your mindset, and that got us.
“But fair play to Hull to fall back, they’re a champion side aren’t they. They’ve played great all year and they crept back into it.
“But a solid performance [from Castleford], I’m happy with it.”
The Tigers got their Super 8s campaign started positively but they next face Wigan at the Jungle, knowing one slip-up may end any chance of a top four finish.
“It’s massive,” Gale said.
“I’m sure they’ll come ready to roll on Friday. I heard Shaun Wane say they’re going to treat every game like a grand final, or something like that.
“So they’ll come ready to roll Friday and so will our boys. I’m looking forward to that. We can only do what we’re capable of.
“Starting off with a win is great, it’s a great way to start the Super 8s.”
