GURPS: Dire Stirges

Following a comment about the Dire Stirge creature that I've been using in my current D&D Next Campaign, here is an attempt at converting it to GURPS.

I didn't really check any of the cost for this, since it makes no sense to me when designing a creature. Instead, I just went for what I thought a Dire Stirge should have, and should be able to do. They are a bit different from D&D Next but more accurate in terms of what I wanted from this monster.
Overall, it's a tough little bugger and that's what I wanted. The usual Modus Operandi for these is to Rush into Close Combat, Grapple with it's 4 Talons (Claw Grapple), then once they have a good grip, plant their Proboscis somewhere (Proboscis Impaling Grapple) and start draining until full (Limited Capacity) before retreating to safety.

Adults (or youngs against smaller targets) might decide to Claw Grapple, then Fly off (Lifting ST) before dropping their targets in order to weaken it before draining.
The Blood Drain is a follow-up attack from a successful Proboscis Impaling Grapple and causes automatic HP damage each turn. The only way to stop it before is to stop the grapple itself or kill the creature.

To add to the "fun", I put an Affliction: Hemophilia linked to the Blood Drain ability. This Hemophilia effect is ONLY linked to the Proboscis Impaling Grapple damage (not other damage the creature will take).
When playing with these, remember that they do NOT fight to kill, but they fight to feed on blood, unless defending a nest or something of course. Once satiated, they just leave.

Anyway, here they are, both in Young and Adult versions.

Adults are just slightly bigger and meaner versions. The main differences are increased DR, increased ST (and lifting ST) and High Pain Threshold. Due to their increased potential Lifting capacity, they adults are more likely to Grapple then Drag their preys before letting them fall.

How do they play? I have no idea!

I'd imagine they are very nasty when encountered in small groups, especially if they start swarming one or two specific low armor/defenses targets. They are not really meant to kill however, but be very scary for a while, before they leave you alone.

If you actually get a chance to try them out, give me feedback on them please. Otherwise, I'll just update once I give them a test ride.
